      Description

      jshell> Bidi.requiresBidi("AAAAAAAAA".toCharArray(), 2,20)
      | Exception java.lang.IllegalArgumentException: Value start 2 is out of range 0 to 20
      | at BidiBase.requiresBidi (BidiBase.java:4543)
      | at Bidi.requiresBidi (Bidi.java:304)
      | at (#2:1)

      The emitted statement "Value start 2 is out of range 0 to 20" is false.
      The exception message is created here [1] and is based on more than the simple size check. This leads to the incorrect message.

      4542 if (0 > start || start > limit || limit > text.length) {
      4543 throw new IllegalArgumentException("Value start " + start +
      4544 " is out of range 0 to " + limit);
      4545 }
